In this study, we aim to investigate the impacts of credit default swaps (CDS) premium as a risk financial indicator on the fluctuations of value of the Turkish lira against the Euro. We try to answer the following questions: Is the CDS premium change among the drivers of EUR/TL exchange rate...

This paper investigates whether there is evidence of structural change in the Brazilian term structure of interest rates. Multivariate cointegration techniques are used to verify this evidence. Two econometrics models are estimated. The first one is a Vector Autoregressive Model with Error...

In this study we estimate and compare the realized range volatility, a novel efficient volatility estimator computed by summing high-low ranges for intra-day intervals, to the recently popularized realized variance estimator obtained by summing squared intra-day returns. Our results derived from...

In the estimation of risk measures such as Value at Risk and Expected shortfall relatively short estimation windows are typically used rendering the estimation error a possibly non-negligible component. In this paper we build upon previous results for the Value at Risk and discuss how the...

This paper presents a tractable model of non-linear dynamics of market returns using a Langevin approach.Due to non-linearity of an interaction potential, the model admits regimes of both small and large return fluctuations. Langevin dynamics are mapped onto an equivalent quantum mechanical (QM)...

Investors can construct commodity benchmarks better aligned with their investment objectives. This is important because common “plain-vanilla” benchmarks, constructed to mimic relative production activity, may be inconsistent with a CIO’s objectives.CIOs can use the Real Asset Sensitivity...

In prior research we highlighted the diversity of real assets in terms of their sensitivities to the equity and bond markets and to macroeconomic factors such as growth and inflation. We now extend our analysis to real asset portfolios. Do portfolios exhibit similar characteristics and...

The paper studies the impact of the sampling frequency on the volatility of financial time series. We suggest to model the dependence of volatility on sampling frequency via delay equations for the underlying prices. It appears that these equations allow to model the price processes with...
